Title: URBAN SURFACE RECYCLING
Accession Number: 00334551
Record Type: Component
Availability: Find a library where document is available Abstract: Over the past decade, pavement construction and maintenance costs have more than doubled while public works budgets have remained relatively constant, sometimes even decreasing. The escalating rise in new street construction and maintenance cost is a direct result of the current OPEC situation, our dependence on foreign oil and the correlation between asphalt and crude oil product prices. Today's Public Works Engineer has fast become maintenance oriented, as he should be. A major concern must be one of increasing the strength and serviceability of existing streets, while adhering to the necessity to economize. The more expensive method of restoring a worn flexible pavement by resurfacing with a strengthening overlay is now often reevaluated in favor of surface recycling and applying a seal coat to waterproof the underlying pavement structure. The idea of recycling pavement sometimes evokes fears that the recycled material may not possess satisfactory quality and will soon fail under traffic loading. Great improvements have been made in quality control, particularly over the past several years, to eliminate uncertainty and upgrade the end result. Work performed using new "Arizona" specifications and Asphalt Recycling and Reclaiming Association (ARRA) standards (1) with rigid inspection bears no resemblance to earlier heater scarifying work. The technology for successfully recycling asphalt pavements has already been developed and is now available to engineers for more extensive usage on urban projects. (Author)
